If your current need is within 10 - 20 mA, then a CD4067 could solve your problem.

You can see the CD4067 as a 16 ways switch.

If you need more help, then post a schematic of what you have in mind to do.

I am trying to use it to switch two different circuits, both has 4 signals.
- circuit one is an RGBS type video signal
- circuit two is an 4-wire touch screen signal

See attached pic. I have two of these relay circuit to switch them now but I believe an analog swtich will do a better job and bring down the "size" too. I do not know much about ICs. but if I can have a diagram drawing, I know how to assemble them together. Would the CD4067 able to do the job for two separate circuits? or I have to use 2 CD4067 since they are 2 separate circuits?
